Huh. I stand corrected; my apologies to the original poster for spreading misinformation. Is the only purpose of having a key skill for no-check rituals that they determine the type of components you use for it, if your DM doesn't just let you burn GP directly (a very common houserule in my experience)?
Pretty much. It's really not in your interest to have them burn GP directly. Let them keep track of their components, it lets you keep a measure of control over what they can do. If Passwall is gonna be a problem in the next dungeon, for example, make it hard to buy the component for that skill. Not so hard they can't do it once or twice, but hard enough that they'll conserve it for when it's valuable (which can mean never using it at all).
